Description
The present invention relates to the supervision and the maintenance of network in comprising the telecommunications network of a large amount of network elements.
Telecommunicatioin network management comprises a large amount of network operation tasks and network operation task.These tasks can roughly be divided into 3 fields: tectonic network, Operation Network and exploitation network.
The operation of network and area of maintenance comprise the daily processing routine of webmaster.These comprise the real-time monitoring of network failure, and alarming processing detects failure location and analysis, and reparation task.
Typical telecommunications network is made up of a large amount of network elements, comprises switching center, base station, transmission point etc.Big network can be made up of tens thousand of network elements.Each network element may be made up of a large amount of separate units again.Because the complex characteristics of this network concept, a large amount of faults can appear in every day in the network, and each fault itself can cause the one or many alarm, alarm perhaps can not occur.Big tens thousand of alarms of network generation every day.For example, the GSM of medium-sized size (global mobile communication) net estimates roughly to generate every day 10000 alarms.
In order to manage and monitoring network, one or more centralized network management systems (NMS) are provided, wherein collect alarm and other net element information with centralized system, the network monitoring personnel can control whole network by work station.The information relevant with alarm with fault can provide to the network operator by different way.A kind of mode is to represent the geographical position and the alarm status thereof of all network elements by graphical map.This graphical map shows the alarm status that makes that the network operator can the fast browsing network.In addition, the text based alarm monitoring is used and can be generated warning information with form more specifically.
Network failure management (FM) based on monitoring alarm, is assessed its seriousness and influence at present, and corresponding startup repair process.The importance of alarm depends primarily on two factors: 1) alarm is to the network element Effect on Performance, and 2) importance of network element.An existing problem of using is the enormous amount alarmed, and many alarms are all produced by same fault, hindered fault regularly and effective monitoring.Another problem is, can't obtain fault immediately to the influence of network performance or the general overview of network element importance (for example Sun Shi traffic carrying capacity).At present, when alarm flow to into network element system, the network operator once checked an alarm according to network operator's resource and experience, if desired, be opened to the long-range MML session of network element, the existing performance measurement of possible procuratorial work is according to measuring the influence of suspected fault to network performance.At present, for fault is determined priority, concentrating reparation effectively is a very effort hindering the most serious fault network element of network performance aspect traffic carrying capacity loss and the quality of service, or even impossible task.On the other hand, detect the fault that can not have a strong impact on network element or network performance, thus can be afterwards, and it is also quite important for example to finish the repair relevant with these faults when some maintenance investigation of carrying out other.The above-mentioned fact is correlated with because carry out at the network element scene safeguard fact-finding process, that especially carries out after normal working hours safeguards that fact-finding process is with high costs.In addition, network element is not worked fully, because fault even may not can send alarm, thereby can't detect fault.
Except alarm, telecommunications network generally comprises performance management (PM) and measures, and this measurement is carried out in network, sends to network management system from network.According to the network condition that is monitored, the capacity of network management system is different with network operator's requirement, and these are measured and sent once in for example per 15,30 or 60 minutes, sent once in per 6,12 or 24 hours, or the like.These measurements may relate to for example call attempt, abandon or blocked call and handover mortality.
Performance management PM is a kind of off-line procedure traditionally, its Collection and analysis 24 hour datas.This is a kind of good method that detects telecommunications network trend and problem, but this process is too slow for the real-time monitoring of network.
An object of the present invention is a kind of online method for monitoring network and system, it can assist more easily detection failure and to the influence of telecommunications network operation of network operator, and identifying needs the most important network element repaired.
Network element provides with structure chart or the ground diagram form that shows on the graphical user interface.According to the present invention, on graphical user interface, provide the network element performance information with graphics mode at the network element symbol, make the network operator just can find to the of paramount importance network element of network operation quickly, perhaps operation is subjected to the most serious network element of fault effects.Can discern the most urgent and important reparation target in this way, thereby available resource is mainly used in these targets.Simultaneously, can detect the alarm that to ignore and network performance or quality of service are seriously reduced.The network element performance information that provides can also be used to locate the problem (for example dormant base station) that does not send alarm.The present invention can also detect and locate the problem that can't see on the transmission path.For example, can't directly monitor another network operator's transfer element, but the deterioration of the network operator oneself of the present invention after can connecting by fault network element performance detects problem.
According to a kind of embodiment of the present invention, on graphical user interface, show the alarm situation of each network element at the network element symbol figure.Like this, the alarm situation that the network operator can the fast browsing network.When showing network element alarming, this graphical display also shows the diagrammatic representation that the present invention illustrates the network element performance.In this way, combined fault management (FM) and performance management (PM) are set up fault and it is to the association between the influence of telecommunications network or network element.The advantage that obtains is tangible: the network operator does not need to follow the tracks of a large amount of alarms, does not need to attempt guessing their influences to network, because the influence of alarm is apparent on screen of the present invention.Many improvement have been realized like this: reduced the traffic carrying capacity loss that the fault work causes with accurately directed reparation fast, network operator's regular works and pure conjecture reduce in a large number, safeguard investigation quantity still less, the general view of the various performances of network is far better, the network monitoring mode is simpler, and monitor staff's training requirement still less.
The performance number that needs to show has the plurality of optional type.The relative deviation form that the performance of network element for example can be used as normal performance provides.Because except the deviation of performance, the diagrammatic representation of network element has provided normal traffic carrying capacity, so can easily detect the most serious element of performance deficiency, determines the urgent order of priority and reparation fast.Diagrammatic representation can followingly realize: by the symbol of each network element on certain object assignment graph user interface, the outward appearance of this object comprises shape, and color and size change according to alarm and performance information.
In an embodiment of the present invention, with absolute value, rather than the relative value form illustrates current and normal performance, and traffic carrying capacity or the indicating device that is directly proportional with traffic carrying capacity are as performance indicator.In this case, relatively the absolute value of the normal performance of different network elements is compared with other element on graphical user interface as can be seen, and each network element is to the relative importance of traffic carrying capacity.When comparing the importance of network element, must use normal performance, because the current performance of different elements (may hinder and distortion for some reason) can't correctly be represented its importance.On the other hand, if the absolute normal performance of network element only is shown, then can determines the priority of network element, but can't obtain their inner case information.
In a preferred embodiment of the present invention, show normal and current absolute performance simultaneously, also represented the inner case of network element, i.e. the current performance of comparing with normal condition (for example traffic carrying capacity).Utilize these diagrammatic representations, the network operator can select the most important network element that has lost most of performance quickly and repair.
In an embodiment of the present invention, calculate normal performance and traffic carrying capacity, and current performance or traffic carrying capacity, if learn with time the average economic profit of the traffic carrying capacity that is unit, the economic loss of then for example calculating network element failure and being caused, and be that unit presents to the network operator with time.Loss can be expressed as the digital numerical value or the diagrammatic representation of absolute value, relative value, and the like various expressions.Repair also can be optimized, and makes to cause the fault of serious economy loss at first to be repaired.
In an embodiment of the present invention, repeatedly, preferably per hour all calculate the normal performance of network element in this sky separately in one day.In another embodiment of the present invention, every day in the week, and in one day repeatedly, the normal performance of per hour all calculating network element separately that preferably should week.In this way, can be effectively with normal performance and traffic carrying capacity along with the moment in one day, and what day variation is taken into account in the week.The peaking capacity time that has than the high call loss ratio may appear at, and for example Monday, from 1 o'clock to 2 o'clock afternoon, and on Sunday, from 8 o'clock to the 9 o'clock morning, traffic carrying capacity was less, and the calling that abandons is also less.If the mean value of complete cycle is used as normal performance, then the change of the caused performance of normal variation of traffic carrying capacity will be expressed as the serious deviation of " normally " performance on the graphical user interface, and this makes monitors more inaccuracy.Because according to the present invention, the normal performance of calculating also can along with in the moment in one day and/or the week what day and change, compare with normal performance, diagrammatic representation of the present invention makes the detection of deterioration of the current performance that alarm is caused want much accurate.

The present invention can be used to monitor network element and send performance measurement data, preferably also sends any telecommunications network (information network) of alarm.But, describe the preferred embodiment of the present invention at European digital mobile communication system GSM (global system for mobile communications) below, but the present invention is not limited to this system.The basic element of character of gsm system discloses with operating in the ETSI/GSM standard.The more specifically description of gsm system is please shown " The GSM System for Mobile Communication ", Palaiseau, France, 1992, ISPR:2-9507 19-0-7 referring to these suggestions and M.Mouly and M.Pautet.
In Fig. 1, network management system NMS is connected to the network element of gsm mobile communication system by data communication network DCN.In this connected, data communication network was meant that NMS and network element can be in order to any the connections and network that is connected with each other.Packet switching network PSN, PCN circuit are connected with local area network (LAN) LAN or wide area network WAN connection is the example that feasible DCN realizes.MS is in order to irrelevant with the interface of net element communication or protocol type and the present invention.According to the difference of network element, the interface or the consultation of employing are different.In the present invention, importantly alarm and performance measurement data can send to network management system NMS from network element.
In the embodiment in figure 1, NMS provides a kind of centralization of following GSM network components: mobile services switching centre MSC comprises Visited Location Registor VLR; Attaching position register HLR comprises equipment identity register EIR and the AC of authentication center, base station controller BSC; Code converter and Sub-multiplexer TCSM; And base station BTS.
Network management system NMS can also provide the interface and the basic monitoring of the non-GSM network equipment.This equipment comprises Short Message Service Center SMSC in Fig. 1, professional interconnection SXC, digital nodes DN2, digital microwave wireless device DMR or the like.In addition, NMS can be connected to intelligent network IN equipment, comprises service control point (SCP) and business management system SMS.
The hardware configuration of network management system and basic operation can be similar to known network management system, only need make amendment to realize network monitoring operation of the present invention to the latter.In a preferred embodiment of the invention, network management system NMS is based on the Nokia NMS/2000 of the Nokia Telecommunications Oy production of Finland.But, have to be noted that the present invention generally can be applied to collect the alarm of telecommunications network and any network management system of performance measurement data.
Below by the hardware configuration of example explanation according to the network management system NMS of first preferred embodiment of the invention.NMS is made up of server and network operator's seat, and network operator's seat can be to use work station or remote terminal.These equipment are connected to local area network (LAN) LAN.If use PC to use, then Fu Jia personal computer PC can be connected to same LAN.In Fig. 1, these servers are by telecommunication server CS, and database server DBS and standby server SBS and combination thereof are formed.For less telecommunications network, for example hardware configuration can comprise the telecommunications and the data server of standby server SBS and combination.
Telecommunication server CS is responsible for the data business volume between network element and the NMS.Data link to data communication network DCN is handled by the independently mediation device R (for example router) that is connected to LAN.The database storage that database server DBS has network management data.For example can adopt relational database.This database can be configured to a plurality of independently table spaces and be used to store different types of data: fault, and performance and configuration data, every kind of data all have the table space of oneself.The size of each table space can be determined separately at given time as required.
If one of database server or telecommunication server break down, then standby server SBS can serve as database server or telecommunication server.This redundancy has increased the fail safe of system, helps upgrading processing.
Operator's seat provides the access of webmaster operation.Using the management of work station WS operation cellular network uses.This WS is equipped with graphic alphanumeric display.In addition, WS can also serve as the client server of one or more remote terminal.All webmasters and monitor task can be undertaken by graphical user interface by work station WS or remote terminal with centralized system.Managed element can be expressed as hierarchical structure, and it can also comprise the digital map of the reality that shows the network element geographical position.According to basic principle of the present invention, on graphical user interface, provide the alarm status and/or the performance data of network element at network element.
These network elements are alarmed in real time or near sending to network management system NMS in real time.NMS is stored in database server DBS from the continuous receiving alarm of managed element with alarm, provides on the graphical user interface of work station WS.
Network element provides with the form that structure chart on the graphical user interface or map show.According to the present invention, the alarm situation of each element shows at the network element symbol in diagrammatic representation (symbol) mode.Alarm can be expressed as for example coloured picture of network element.If NMS is from the network element receiving alarm, then coloured picture (perhaps other symbol) is presented on the corresponding network element symbol of graphical user interface immediately.The alarm cancellation (a kind of typical operation) that arrives from the network of monitoring shows that specific warnings is no longer valid, and promptly fault is removed.When receiving the alarm cancellation, NMS cancels coloured picture on the corresponding network element symbol of graphical user interface.The color of picture can depend on the importance of alarm.In first preferred embodiment of the present invention, the importance according to alarm is divided into 3 different classes with alarm: urgent, serious and slight, it is red that color is respectively, orange colour and yellow.Like this, the network operator obtains the general survey of network alarm situation easily.
In addition,, on graphical user interface, provide the performance information of network element with graphics mode, make operator can detect the network element that the most important network element of network operation or operation is subjected to fault effects most at the network element symbol according to the present invention.In this way, can detect urgent and the most important reparation target, available resources are mainly used in this target.Performance information can show simultaneously with alarm, perhaps not show these warning information.Under first kind of situation, can detect and to ignore and can not make the alarm that network performance or quality of service descend significantly.
NMS receives performance measurement data PM continuously from managed element, and measurement data is stored among the data server DBS.Network element is according to network element, the PM data type, and factors such as telecommunication system send the PM measurement result with specific interval.Measurement result can be for example per 15,30 or 60 minutes, sent once in per 6,12 or 24 hours.The polytype of different measuring is important measurement but have only a few, relatively accurately the performance of indication network.This measurement can be called performance management PM indicating device.The example of suitable performance management indicator comprises and the call attempt number of times, abandons or measurement that the calling of blocking or handover mortality are associated.The PM indicating device has been indicated the performance of given time network best, and it depends on factors such as network element, telecommunications network type.Virtual network operator can be selected the PM indicating device and the combination thereof of suitable its purpose.
NMS can calculate normal value, currency and/or with the relative or absolute deviation of normal value.Currency, promptly current performance can be according to the measured value that last time, measurement report obtained, and it can be a short time period, and for example one hour time was gone up the mean value of the PM indicator value of collecting.Normal value, promptly normal performance can be longer measuring period, preferably for example some weeks are gone up the mean value of the PM indicator value of collecting.
Following let us is by the calculating of example investigation with the deviation of PM measurement result.NMS receives the PM measurement result that network element is not handled, and may handle again it, for example converts thereof into ascii table.Then, NMS can calculate key performance indicating device KPI according to different measuring, perhaps directly uses the PM measurement result.Then, NMS measures and the new deviation (PM measurement result or the KPI that obtains according to it) that is stored in the former normal value (mean value) among the database D BS, this deviation is stored in the deviation chart of database D BS.This database comprises this week normal value hourly, and the used normal value of given time was selected according to this hour in this week.Then, NMS cancels measurement result or KPI value the earliest in normal value calculated data storehouse (having N position), and adds up-to-date value.Then, NMS calculates the mean value of new normal value as N value in the calculated data storehouse, and stores this value.At last, NMS upgrades the corresponding PM graphical display of network element on the graphical user interface.
Receive the PM measurement result that relates to network element at every turn, just network element is carried out said process.The front was carried, and this may carry out once in for example per 15,30 or 60 minutes.Alarm can present in real time, and the PM deviation then provides on graphical user interface in mode quasi real time.Can be for example should week per hour all be that each different PM measures (for example traffic carrying capacity or blocked call) and calculates a normal value.This needs a large amount of amount of calculation and database volume.For example, measure (for example traffic carrying capacity and blocked call), and telecommunications network comprises 1000 network elements, then the 2*1000*24*7=336000 data set is stored among the database D BS if observe two PM.
It is that each network element or one or more PM indicating device (measurement) provide one of following at least performance information item that NMS can use graphical user interface: normal value, currency and/or with the relative value or the absolute deviation of normal value.Performance preferably provides at the network element symbol figureization.For example, diagrammatic representation can followingly realize: on graphical user interface, the symbol of each network element is provided by an object, and the outward appearance of this object comprises that profile, color and size change with performance information and alarm.
Fig. 3 has illustrated the figured a kind of mode that realizes relative deviation or absolute deviation.Each network element (cylinder 31,32 and 33 of base station BTS 1, BTS2 and BTS3) shows a cylinder.The height of cylinder shows the absolute deviation with normal value.The color of cylinder can also change with the increase of deviation, makes that big deviation is easier on screen to discover.If there is not cylinder to exist, then performance is in range of normal value.Also may be for example in the deviation cylinder with coloured picture 36 display alarms.Only provide aberrations in property and inform that just operator has the network element of lowest performance, still do not determine the priority of network element with any alternate manner.In this case, at first repair these network elements.If mis-behave, but not alarm, then network element may hinder for some reason and can't send alarm, and perhaps mis-behave is caused by another component failure, can't directly see on screen.Therefore, can detect the dissimilar of hiding fault according to performance monitoring of the present invention.
Fig. 4 has illustrated second display mode with respect to the current relative performance of normal performance.The cylinder 41,42 and 43 of Fig. 4 has provided the normal performance (100%) of base station BTS 1, BTS2 and BTS3.Have color cylinder 41A, 42A and 43A in the cylinder have shown the percentage of current performance with normal performance.In this case, relative deviation is 100-p%.This expression makes operator be easy to observe the deviate with normal value.Have color cylinder low more, the deterioration degree of performance is high more.In addition, can also for example present alarm with the form of alarming picture 36.Cylinder 41 to 43 has equal height, thereby can't determine the priority of network element in view of the above.
It is noted that according to the present invention, can provide the performance management indicator of arbitrary quantity.Fig. 5 has provided and has used two PM indicating devices at the same time, and promptly traffic value (for example being the calling of unit with time) and when abandoning calling rate presents a kind of mode of relative deviation.Cylinder 51 and 52 shows normal performance number: highly represent 100% traffic carrying capacity, diameter represents that 100% abandons calling rate.Base station BTS 1 situation is normal, therefore, has only provided cylinder 51 on the graphical user interface.Base station BTS 2 breaks down, and this fault has also caused on coloured picture of performance cylinder and demonstrates fault warning.Because this fault, traffic carrying capacity has reduced p%, and this minimizing represents that by coloured expansion 52A of cylinder 52 the two diameter is identical.The height that expands 52A directly is proportional to the minimizing of traffic carrying capacity.Simultaneously, the calling rate that abandons also increases r%, and this increase by the diameter 52B of cylinder 52 is represented, and may be expressed as change in color.The increase of diameter directly is proportional to the increase that abandons calling rate.Like this, the network operator is by profile and change in color, and the increase of size seen the fault network element, and this helps to detect a large amount of elements the network element of needs reparation very much from screen.Cylinder 51 and 52 is highly equal, thereby can't determine the priority of network element according to them.
Can also be with absolute value, rather than the form of relative value provides current and normal performance.The absolute value of different network elements can compare mutually, like this, can see the relative importance of each network element on graphical user interface.But, this absolute value more only with traffic carrying capacity or just meaningful during as performance indicator corresponding to the indicating device of traffic carrying capacity.In addition, the current and normal performance that provides is informed the current performance (for example traffic carrying capacity) that the network operator compares with normal condition.The most important network element that the needs that these diagrammatic representations make the network operator to select to have lost most of performance are quickly repaired.
Fig. 6 has illustrated a kind of mode that presents normal performance, current performance and deviation with the absolute value form.Cylinder 61,62,63 and 64 height have been indicated for example their absolute performance, regular traffic amount.Therefore, the height of cylinder has directly been indicated the importance to traffic carrying capacity of this network element with respect to other network element.In Fig. 6, be BTS1, BTS4, BTS2 and BTS3 to the significance sequence of traffic carrying capacity.Have color cylinder 61A, 62A, 63A and 64A in the cylinder 61 to 64 have indicated current performance (traffic carrying capacity).Therefore, it can also be seen that fault is to the network element Effect on Performance.In Fig. 6, according to absoluteness loss of energy degree, repairing order is BTS1, BTS2, BTS3 and BTS4.According to the relativity loss of energy, this order is different fully: BTS3, BTS1, BTS2 and BTS4.On the other hand, according to the alarm number of times, this order is BTS2, BTS3, BTS1 and BTS4.Therefore, operator can receive a large amount of information quickly, and according to these information, operator can draw the reparation order.The reparation order of Fig. 6 is BTS1, BTS3, BTS2 and BTS4 preferably.
Fig. 7 has illustrated a kind of mode of the absolute value that only presents normal performance.Cylinder 71,72,73,74 and 75 height show their traffic carrying capacity among Fig. 7, and thereby show their important order.In addition, for example show these alarms with coloured picture 76.But these embodiment do not take the performance loss of reality into account.
In an embodiment of the present invention, calculate normal performance or traffic carrying capacity and current performance or traffic carrying capacity, average profit in traffic carrying capacity, be under the known situation of commercial value (for example be unit and/or be unit with time) with the performance, be not out of order if discover, the economic loss (for example being unit) of then calculating network element and being generated with time, and present to the network operator.This loss can be expressed as the absolute value form, or the digital value of relative value form or diagrammatic representation.Fig. 7 shows the caused loss of fault on the top of cylinder, hour being unit (for example FIM/ hour).On this basis, can select the network element of need repairing that causes heavy losses.The similar presentation mode of this loss can be applied to represent other diagrammatic representation of performance, or only is applied to alarm and does not comprise other performance information.
It is noted that top description only discloses the performance information that presents network element, in some modes of monitoring and analysis of failure.To those skilled in the art, obviously under the prerequisite that does not depart from the disclosed scope and spirit of appended claim book, can carry out different changes and improvements.
